The links that connect concepts are called conceptual relations. Two of them have particular relevance in the organization of conceptual knowledge: taxonomic and thematic relations. Early research in the 80`s focused on analyzing the existence of a primacy of one kind of conceptual relation over the other in children and adults. Recent studies explore the neuroanatomical bases of these conceptual relations. The present work constitutes a revision of the most relevant studies about taxonomic and thematic conceptual relations, including developmental studies, research on neuroanatomical bases and available ways of assessment. The revised articles state that thematic and taxonomic conceptual relations involve dissociable cognitive processes that can be acquired and damaged independently and have independent neuroanatomical basis. Futures lines of research are also suggested.
Keywords: conceptual relations, taxonomic relations, thematic relations, conceptual knowledge, semantics.
